GERM-PROOF PACKAGE.

SPECIFICATION forming 'part of Letters Patent No. 616,472, datedDecember 27, 1898.

Application filed January 3, 1898. Serial No. 665,239. (No inodel.)

To all whom it may concern..-

Be it known that I, WVILL M. KINNARD, a citizen of the United States,and a resident of Dayton, in the county of Montgomery and State of Ohio,have invented certain new and useful Improvements in Germ-ProofPackages, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

My invention relates to an improvement in germ-proof packages made,preferably, of paper, cardboard, or similar material, and is intended tobe used for the package and transportation of such substances as arelikely to become injured by exposure to the atmosphere and the action ofthe microbes or the deposits of insects, such as flies and the like, andatmospheric changes.

Great difficultyhas been found in packing in a satisfactory way foodproducts of various kinds, such as cereals ground and prepared for use,as well as many other substances, because it has been difficult to putthem in a light and convenient package that was airtight, and afterseveral months some of these packages would be found to be wormy. It isnecessary when handling these products that they be put up in packagesthat are light and inexpensive, neat, and attractive.

It is to overcome the difficulties described that I have made myinvention, which will be more fully hereinafter described.

In the accompanying drawings, Figure l is a perspective view of thepackage closed. Fig. 2 is a top plan View of the package collapsed, oneend being complete and the other end wanting the attachment shown inFig. 5. Fig. 3 is a vertical cross-section of the package, the upper endopen. Fig. isaperspective view of the package with both ends open. Fig.5 is a perspective view of the supplemental cud.

Like letters of reference indicate identical parts in all the figures.

A A are the side walls of an ordinary rectangular box, and it ispreferably made in the form of a collapsible or knockdown box, as shownin Fig. 2, and the single piece forming the four sides A A is creased soas to form the four corners, and the ends of it are brought together andglued in the usual manner, the ends of the box B lying out fiat to befolded into position, as shown in Figs. 3 and 4.. In

this form, collapsed or knocked down, as

shown in Fig. 2, the boxes are kept until they are ready to be used.They are then brought into the form shown in Fig. at and the two endsput in place and secured, forming a rectangular box. There is nothingnew in the construction of boxes as thus described except the manner ofconstructing the ends in order to form an overlapping flange when thebox is closed and an interior flange, as hereinafter described.

The end pieces B are provided with extensions or wings I), and when thebox is brought into shape, as shown in Figs. 1, 3, and 4., these wingsare folded over the outside walls A A and secured in place. To make thejoints more secure, I provide for the ends supplemental pieces, as shownin Fig. 5, (marked 0.) This supplemental piece 0 is formed with sideflanges or wings a and is glued to the ends B, as seen at the upper endof Fig. 2 and in Figs. 3 and 4. The lower end B in Fig. 2 shows the formof the blank collapsed before the supplemental ends 0 are added, whilethe upper end shows it after the supplemental end 0 has been put inplace, where it is securely glued. I have shown and described the endsformed with a supplemental piece C, glued to the ends B, as the simplestand most eco nomical way of constructing these ends. Of course it ispossible to make the ends B O in one solid piece. The ends thus formedare provided with double flanges or wings, as clearly appears in Fig. 4.Two of these inner wings are usuallybeveled off at their corners, so asto cause them to pass more easily within the walls of the box. When thebox is ready to be closed, the glue-brush is passed between the twowings or flanges c I) clear around the end, depositing glue on the sidesof both the flanges b c. The end is then folded into place, the wings cpassing inside the walls A A and the wings I) passing outside the wallsA A, securely embracing the ends of these walls between them andproducing a perfectly airtight joint. I prefer in putting these ends inposition to use a former which will just fit snugly the end of the boxand extend up the distance of the outer wing b. The pressure of thisformer against the sides or wings I) b causes these wings to be gluedsecurely to the sides A A. A similar former may be inserted to pressoutwardly against the wings a c, if desired, though ordinarily thecontents with which the box is filled will answer this purpose. Ofcourse a former on the inside could only be used when the bottom end wasbeing secured in place. In practice these boxes remain in theircollapsed condition until ready for use. One end is then brought intoplace and the box placed in the former and filled. Then the other or topend is secured in place and the box turned over and that end put in theformer. In that way the contents serve to press outwardly sufficientlyto insure a perfectly-tight joint.

The walls A A being made of a single piece, the ends of which aresecurely lapped and fastened, (and they may be lapped to any desirableextent,) there is no joint or opening, as the overlap is of such anextent as to prevent all possibility of any opening. The ends of thewalls being embraced between the wings a b, a perfectly-tight joint issecured impervious to air or moisture. If waterproof material is used,it becomes a waterproof as well as an air-tight vessel, and the contentswill remain unaffected by the changes or conditions of the atmosphere orby moisture, and it can be used to hold liquids provided such liquids donotaffect the glue or a glue is used which will not be affected byliquids.

I have described my package in the preferred form-that is, what iscalled a collapsible orknockdown box allin one piece. It will, however,be readily understood that the box may be made perfectly practical inthree pieces or in two pieces--that is, with both of the endsseparate,or with one of them, the lid or top, separate. In that case allfour sides of the lid or end will have the double flanges b c to fitover and embrace the four walls of the package,the only diiference beingthat this lid or these ends are made separate. It will also beunderstood that where the entire box is made in one piece, the outer lidor end B beingintegral with one of the walls, the inner flap at thatside, as shown at c' in Fig. 4, is not absolutely necessary and may beomitted, because the wall on the side to which the lid is attached andthe lid itself are of one single piece of material in that construction,and of course there is no joint at that point.

I am aware that paper boxes have been made in which the lid was providedwith two flanges to pass down within the walls of the box and athirdflange formed by an extension of the lid folded back upon itself toform' a double flange, the inner one passing down within the walls ofthebox and the outer one extending loose and free to serve as a handlefor opening or closing the box, and I do not claim any suchconstruction, but limit myself to the double flanges embracing andattached to the walls to produce a close and air-tight 'oint.

J Having thus described my invention, what I claim, and desire to secureby Letters Pat= cut, is-

Y 1. A germ-proof box or package, the six walls of which are made from asingle blank, and the ends provided with two or more extensions adaptedto be secured to the outside of the box and a supplemental end securedto said first-mentioned end and provided with two or more extensions orwings adapted to be seen red to the inner sides of the box,substantially as and for the purpose described.

2. Agerm-proof package consisting of four side walls and two end wallswith two supplemental end walls; the double ends being provided withdouble wings or flanges to embrace between them the side walls of thepackage, substantially as described.

3. In combination with the ends of a germproof package having wings orextensions to fasten over the outer edges of the walls of the package,the supplemental ends 0, provided with flaps or extensions 0, to fastenwithin the side walls of the package and the two embrace the ends of thesame, substantially as and for the purpose described.

4. A germ-proof collapsible package or box, the ends of which areprovided with extensions b, b, and with a supplemental end 0, having theflaps or extensions 0, c, substantially as and for the purposedescribed.

5. A germ-proof package, one or both of whose sides or ends are providedwith double ends and double flanges to embrace the edges of the othersides or walls in the manner described to form an air-tight joint,substantially as and for the purpose described.
